Friend quizzes continued to be popular on our list of growing Facebook applications as measured by monthly active users this week. There were also a few Page tab applications, and the Are YOU Interested? dating app, a photo app, calendar and BandPage by RootMusic. The titles on our list gained the most MAU of any apps on the platform, growing from between 464,800 and 4.7 million MAU, based on AppData, our data tracking service covering traffic growth for apps on Facebook.

21 questions grew by 2.8 million MAU this week, Truth Game by 966,700 MAU, Between You and Me grew by 906,300 MAU, Truths About You by 795,200 MAU and Get Revealed grew by 679,600 MAU. Each of these friend quiz apps basically does the same thing, asking the user questions about their friends, then posting the answer either to the user’s Wall or to that of their friend.
